--- Comment #1 from Martin Sebor <msebor at gcc dot gnu.org> ---
I don't see the reported error with today's trunk (r221193) but rather a
different one.

After configuring like so:

$ /src/gcc-trunk-git/configure --disable-multilib --enable-checking=release
--with-build-config=bootstrap-lto --enable-languages=c

and making profiledboostrap:

$ nice make -j16 profiledbootstrap

the build fails with:

profiling:/build/gcc-65313/libcpp/lex.gcda:Merge mismatch for function 0
get_d.c: In function '__gmpn_get_d':
get_d.c:490:1: error: the control flow of function '__gmpn_get_d' does not
match its profile data (counter 'arcs') [-Werror=coverage-mismatch]
 }
 ^
